On March 6, President Trump issued a replacement Executive Order (EO) for the previous ones he had issued regarding immigration from several countries. He did this, it seems, to address concerns about constitutionality of the first EO. The Department of Justice immediately filed a “Notice” with the United States District Court in the Western District of Washington, one of the federals court that had issued a nationwide emergency injunction against enforcement of the original EO. This injunction remains in force as I write this post, having been upheld by the Ninth Circuit. The Executive Branch is taking the position that the new EO differs from the old one in ways that mean it can be enforced effective immediately. The Attorneys General of Washington and Minnesota, now joined by Attorneys General from New York and Massachussetts, oppose this for two, related reasons. The AGs argue, on behalf of their respective states, that 1) the new EO largely duplicates the old EO and 2) that the Executive Branch cannot simply deem itself no longer subject to an injunction issued by the Judicial Branch. That second claim is strikingly important even though it does not go to the merits of the first claim or to the question of the ultimate constitutionality of either EO. Rather, the second claim goes to the question of whether the Executive Branch must demonstrate to the District Court that the original injunction does not apply to the new EO based on the law applicable to modifying or removing federal injunction or that such modification or removal should be entered by the District Court. In other words, the AGs claim that President Trump is seeking to free the Executive from the injunction by fiat when in fact he does not have the authority to do this. Below is the Notice filed by the DOJ on behalf of the President and the AGs brief in response, annotated by me to assist nonlawyers in following each side’s arguments.
